So I read this on the wiki: "The format assumes an implicit rail 0 which cannot be explicitly started or ended. Instead, it is present from the beginning of the route to the end, and it marks the rail the player's train drives on. All other rails in the CSV format are purely visual and have no functional purpose."
This implies to me that if you have a complex track layout, and you want to create multiple "activities" on it, that you must rebuild the route.
For example, this would make it very difficult to take a two track route and allow it to be run in both directions. You'd almost have to tear up all the track through the scenery and re-lay the track 0 and then create the other decorative tracks.
Am I correct?
Thanks,
